Salvia connivens Methanolic Extract Against Spodoptera frugiperda and Tenebrio molitor and Its Effect on Poecilia reticulata and Danio rerio. Toxics 2025, 13, 94. https://doi. Abstract: Spodoptera frugiperda (Lepidoptera: Noctuidae) and Tenebrio molitor (Coleoptera: Tenebrionidae) are two prominent pests of maize and its stored grains, respectively...

Spodoptera frugiperda (Lepidoptera: Noctuidae) and Tenebrio molitor (Coleoptera: Tenebrionidae) are two prominent pests of maize and its stored grains, respectively. Botanical pesticides have been proposed as an alternative for their management. This study evaluated the insecticidal activity of Salvia connivens (Lamiaceae) methanolic extract and ro...

Resumen El cambio climático y la dependencia de combustibles fósiles han aumentado la necesidad de encontrar fuentes alternativas de energía. Los biocombustibles, en particular el biodiésel, han surgido como una alternativa prometedora para disminuir el uso de combustibles convencionales como el diésel. En este estudio se investigó la conversión de...

Las arcillas por sus propiedades, son empleadas como materia prima en la elaboración de membranas, debido a que se aglomeran fácilmente y poseen características de intercambio iónico, así como capacidad de adsorción para el tratamiento del agua. El objetivo de este estudio fue utilizar las arcillas mexicanas para obtener membranas porosas y con ell...

Spodoptera frugiperda is the main pest of maize. One of the alternatives proposed for its control is the implementation of products of botanical origin, such as those derived from Ricinus communis. In this work, the insecticidal and insectistatic activities of methanolic and hydrolyzed methanolic extracts of the aerial parts of R. communis and kaem...

For the management of Spodoptera frugiperda, botanical extracts have been used to reduce the environmental impacts of synthetic chemical pesticides. In the present investigation, the insecticidal activity of the acetonic and methanolic extracts of Heterotheca inuloides (Asteraceae) and of the main compound 7-hydroxy-3,4-dihydrocadalene on this pest...

Lignocellulosic biomass is a source of carbohydrates that can be used in the production of biogas. The aim of this study was to obtain biogas from biomass waste (leaves, stems and seed bagasse) of Ricinus communis, applying pretreatments such as temperature and humidity. We examined the effect of these pretreatments on the biomass, two enzymatic pr...

Nanomaterials (NMs) are unique for their characteristics (strength, surface area, electrical, and optical properties) that are derived from the size (<100 nm). For those specific properties, the NMs are applied on environmental remediation, electronic industry, energy production, cosmetic industry, medicine, and other areas of material science, sho...

Ricinus communis is a species distributed worldwide. Its seeds are used to produce castor oil, which can be used for the production of biofuels; yield improvement can be achieved with elicitors that are substances of biological origin that can induce increased productivity of primary and secondary metabolism, when applied to plants. Salicylic acid...

Secondary plant metabolites with a specific function are a diverse group of molecules responsible for adapting the plant to its environment. Within the adaptation of plants is the defense against herbivores and pathogens. Among the specialized metabolites is the group of alkaloids, encompassing the capsaicinoids. Capsaicinoids are molecules found i...

Castor bean (Ricinus communis L.) is an oleaginous plant of economic importance due to its different industrial applications. Edaphic characteristics are used to determine the viability of places considered as suitable to obtain castor oil. The objectives of this study were to determine the edaphic characteristics and oil content of R. communis, an...

Spodoptera frugiperda (Smith) (Lepidoptera: Noctuidae) is one of the most damaging pests in maize crops. In order to manage it, synthetic insecticides such as diamides, neonicotinoids, and pyrethroids are used, but they present a risk for humans and the environment. Investigations of safer alternatives include the use of natural extracts. Thus, thi...

Castor bean (Ricinus communis) seeds contain ricinine, an alkaloid with insecticidal and insectistatic activities. Elicitation with salicylic acid (SA) has proven to stress R. communis and might modify the ricinine concentration. The aim of this study was to evaluate the concentration of ricinine in the bagasse of seeds from R. communis elicited wi...

Fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), infests more than 80 crop species and is the principal pest of maize (Zea mays L. (Poaceae) in Mexico. Although insecticides are used to control the pest, they can cause environmental damage and negatively affect human health. Essential oils are an alternate for managing th...

In recent decades, agrochemicals have been used in agriculture to increase crop yields and quality and avoid losses due to pests. However, the use of these substances often imply environmental contamination and potential health risks. To move towards a more sustainable agriculture with less undesirable effects to human health, a novel line of resea...

In order to evaluate the presence of heavy metals, samples of seawater were taken over one year, covering the four seasons, at three sites along a 100km section of the Mexican Pacific Ocean coastline, which extends for 7338km. The central point was Playa Blanca, Guerrero, while the two extremes of the sampling area are open sea regions (El Calvario...
